Association of metabolites with systolic blood pressure (SBP) on low- or high-sodium intake based on random forest analysis. Box plots of discriminating importance scores (Z-scores) from up to 500 regression trees are shown for each metabolite analyzed. ShadowMax was the maximum Z-score calculated from randomly permuted features. Metabolites with average Z-scores greater than average shadowMax are shown in green.
